Peziza cervaria, Phil., in Stevenson's Myco. Scot., p. 308 ; 

 Brit.. Disc, p. 100. 



On roedeer dung. 



Ascophoie \—2 lines broad. 



This species closely resembles P. hepatica (Batsch), but 

 differs in having much smaller spores, and slenderer para- 

 ph vses, not thickened at the apices, and forked. 



Not examined. The above is from Brit. Disc, p. 100.

 rotten pine-wood. 



Karsten's var. ligniaria only differs in growing on wet 

 rotten wood.

 Sacc, Syll., viii. n. 576. 



Ascophore sessile, at first closed and subglobose then 

 expanding and becoming almost plane and scutellate, fleshy, 

 fragile, glabrous, blackish-chestnut, 1-1 J cm. across ; exci- 

 pulum parenchymatous, cortical cells 15-20 ll diameter ; asci
